## Long description

The UNIVERSAL UA - UAFX - Knuckles '92 Rev F Dual Rec Amplifier is a compact two-channel recording and instrument amplifier designed for controlled gain staging and straightforward signal routing. Built for integration into recording chains, pedalboards and live capture setups, this unit provides independent amplification paths for two inputs, enabling consistent level control for studio tracking and direct instrument recording.

This dual rec amplifier offers precise gain control on both channels, low-noise signal amplification and a compact footprint for easy placement in pedalboard and rack configurations. Its straightforward signal routing simplifies integration with DI boxes, audio interfaces and multitrack recorders. The design focuses on consistent, repeatable levels and compatibility with a variety of instruments and recording workflows.

How to use
Connect instrument outputs or pedal chain sends to the amplifier inputs and route the amplifier outputs to your audio interface, recorder or mixer. Set the gain controls for each channel to achieve the desired recording level while avoiding clipping. Use the unit as a front-end preamplifier for direct recording or as a level-matching device when integrating multiple signal sources. When using with pedals, place the amplifier after effects that you want captured at a fixed level.
Usage recommendations
For optimal results, set input gain conservatively and monitor levels via your recorder or interface meters. When recording, perform a quick level check and adjust gain to provide adequate headroom. Use shielded cables for instrument and output connections to minimize noise, and place the amplifier on a stable surface or secured to a pedalboard to maintain consistent connections.
